Objective:
To examine the intrarater reliability, interrater reliability, and responsiveness of the Activities of Daily Living Computerized Adaptive Testing system (ADL CAT) in patients with stroke.
Design:
One repeated-measures design (at an interval of 7d) was used to examine the intrarater reliability and interrater reliability of the ADL CAT. For the responsiveness study, participants were assessed with the ADL CAT at admission to the rehabilitation ward and at discharge from the hospital.
Setting:
Eight rehabilitation units.
Participants:
Three different (nonoverlapping) groups of patients (N=157) were recruited. Fifty-five and 42 outpatients with chronic stroke participated in the intrarater and interrater reliability studies, respectively; 60 inpatients who had recently had a stroke participated in the responsiveness study.
Interventions:
Not applicable.
Main Outcome Measure Adl Cat Results:
The intraclass correlation coefficient values were .94 and .80 for the ADL CAT in the intrarater reliability and interrater reliability studies, respectively. The classical test theory-based minimal detectable change values were 6.5 and 9.5 for the ADL CAT in the intrarater reliability and interrater reliability studies, respectively. The Kazis' effect size and standardized response mean of the ADL CAT were moderate (.62-.73).
Conclusions:
The ADL CAT has good intrarater reliability and interrater reliability in outpatients with chronic stroke, and sufficient responsiveness in inpatients with stroke undergoing inpatient rehabilitation. Further investigations on the responsiveness of the ADL CAT in outpatients are needed to obtain more evidence on the utility of the ADL CAT.
